See text Vivianiaceae was a family of flowering plants placed in the order Geraniales.

The family name is derived from the genus Viviania Cav.

[1] There are around 1-4 genera in Vivianiaceae (Araeoandra, Caesarea, Cissarobryon, Viviania; with all of four genera can be merged into one genus), and under the APG III system the genera from Ledocarpaceae - Balbisia (incl.

Ledocarpon), Rhynchotheca, and Wendtia - are now included within the Vivianiaceae.

[2] A relationship with Caryophyllales, was formerly suggested; but morphology (S-plastids) and chemistry are close to Geraniales.
